replace *(.init_array .init_array.*) with KEEP(*(.init_array .init_array.*)). The KEEP statement within a linker script will instruct the linker to keep the specified section, even if no symbols inside it are referenced. This statement is used within the SECTIONS section of the linker script. This becomes relevant when garbage collection is performed at link time, enabled by passing the --gc-sections switch to the linker. The KEEP statement instructs the linker to use the specified section as a root node when creating a dependency graph, looking for unused sections. Essentially forcing the section to be marked as used. Signed-off-by: cuiziwei <cuiziwei@xiaomi.com>

/* The STM32F407VG has 1024Kb of FLASH beginning at address 0x0800:0000 and
|
|
* 192Kb of SRAM. SRAM is split up into three blocks:
|
|
*
|
|
* 1) 112Kb of SRAM beginning at address 0x2000:0000
|
|
* 2) 16Kb of SRAM beginning at address 0x2001:c000
|
|
* 3) 64Kb of CCM SRAM beginning at address 0x1000:0000
|
|
*
|
|
* When booting from FLASH, FLASH memory is aliased to address 0x0000:0000
|
|
* where the code expects to begin execution by jumping to the entry point in
|
|
* the 0x0800:0000 address
|
